PICTURE PROCESSING METHOD IN EMBEDDED SYSTEM

An embodiment of the present invention provides a picture processing method in an embedded system. The picture processing method includes: performing a bit setting operation on an input/output register corresponding to a communication GPIO port of a camera module in the embedded system, so as to improve a picture collection speed of the camera module; compressing a collected picture using a preset picture compression algorithm and transmitting the compressed picture to a picture preprocessing unit in the embedded system; and filtering out, by the picture preprocessing unit, a picture background using a preset filtering algorithm to obtain picture features of a target object in the picture. With the picture processing method, requirements for an occupied memory resource are balanced while a picture collection speed and a picture data processing speed are increased.
